(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A 1234. pF capacitor and a 5.6 × 106 ohm resistor are connected in series to 78. volts EMF. Approximately how long does it take the capacitor to become almost fully charged?

2. Relevant equations

Vf=Vo(1-e^(-t/RC))

3. The attempt at a solution

I'm not sure if the equation I'm using is correct. I know there is one that has Q in it but couldn't find it. If there is Q in it how do I link it to volts? Through C=Q/Z?
